Filed June 22, 1928 fer'nE Fax' Patented Dec. 9, 1930 UNITED STATES PATENT oFFlcE VERNIE A. FOX, F DETROIT, MICHIGAN, ASSIGNOIt TO YOUNG BROTHERS COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN coNvEYnR nAcK Application led June 22, 1928.

The present invention pertains to a novel rack of the general typecarried by a conveyer in the handling of sheet metal plates or similar articles that have been coated with paint,

varnish, enamel and the like.

The principal obj ect of the invention is to provide a device of this character constructed of a small number of simple parts and easily assembled. The frame of such a carrier consists of a yoke, and according to the present invention the ends of the yoke are seated in the flanges of channel links comprised in the conveyer chains.

The invention is fully disclosed by way of example in the following' description and in the accompanying drawings, in which- Figure 1 is a transverse section of a convever showing the rack in elevation;

Figure 2 is a detail section on the line 2 2 of Figure 1;

Figure 3 is a section on the line 3-3 of Figure 1; and

Fig. 4 is a section on the line 4 4 o-f Figure 1.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 1 is illustrated a track consisting of opposed and parallel angle members 1 on each of which is mounted a rail 2. An endless conveyer rides upon the track and is comprised of two chains associated with the rails. Each of the chains is comprised of outer links 3 and inner links 4, partly of channel cross section as will presently appear, which overlap one another at their ends as shown in Figure 2, and wherein these ends are joined by transverse pins 5 provided with surrounding rollers 6 resting on the rails 2. This construction provides efficient traction of the conveyer chains on the rails 2 Without excessive friction.

It will be seen in Figure 2 that the links 3 are of a simple character while the other links 4 are of heavier construction and provided with pairs of integrakoutwardly extending ears 7 which impart a channel formation tothese links as shown more clearly in Figure 1. The frame 8 of the rack is a wire bent into the shape of a yoke and having its Serial No. 287,529.V

ends passed throughsuitable apertures in the ears 7. Between each pair of ears 7 is positioned a strap 9 having a hub 10 with an o-pening 11 for receiving the same yoke end that passes through the adjacent ears. As shown in Figure 2, the wire comprising the yoke S is of non-circular cross section, and the opening 11 is formed to receive the wire in a neat fit, whereby a locking effect between the straps and the yoke ends is obtained.

rI'he straps at the ends of each yoke are joined by a base bar 12 which is also of angular configuration. At intervals along the bar, shelf members 13 are secured by spotwelding or in any other suitable manner. Intermediate rods 14 are extended from the back of the yoke through the shelf members and to the lower flange of the base member 12. The rods 14 have their ends bent at right angles as at 15 for soldering or welding to the back of the yoke. and the base member. The sides of the yoke and also the intermediate members 14 are bent rearwardly near their lower ends as at 16 and 17 respectively for the purpose of giving the rack an inclined position. The sheet metal articles 18 to be moved by the conveyer are placed one on each rack, with the lower edge thereof resting on the shelf members 13, while the article itself is inclined against the yoke and intermediate members 14.

Although a speciiic embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

lThat I claim is 1. In a conveyer, opposed channel members, a yoke having its ends passed through the flanges of said members, straps secured to said ends between said flanges, and a base bar connecting said straps.

2. In a conveyer, opposed channel members, a yoke having its ends passed through the flanges of said members, straps secured to said ends between said flanges, a base bar connecting said straps, and shelf members secured to said bar.

3. In a conveyor, opposed channel memkbers a yoke having its ends passed through the danges of said members, straps secured to said ends between said flanges, a base bar connecting said straps, shelf members secured to said bar, and intermediate rods extending from the back of said yoke to said bar and passing through said shelf members.

4. In a conveyer, opposed Channel members, a yoke of noncireular cross section having its ends passed through theflanges of said members, straps disposed between said anges, the ends of said yoke being passed through said straps and iitted therein, andV a base bar connecting said straps. l 5. In a conveyer, a pair of chains each comprising a row of simple links and a row of channel links, the members of each roW of links being overlapped at their ends, pins assed through said overlapped ends and Joining the two vrows of links of each chain,

rollers surrounding said pins, yokes connecting said chains and having their ends passed through the fianges of said Channel members, and a base member connectingV the ends of each yoke. y

In testimony whereof I aflix my signature.
